Re: 6 pm: Pre-episode party
Uma is here at the party because she is a party person. Also she has a lot of unpacking and arranging a new apartment to do, so that's lame and a party is a much better idea. And of course, she wanted to support her brother who was supporting his boyfriend. She's gone to say hi to Tony and Nat. She promised to be on her best behaviour. And then she would have gone for a drink.
